Numerical differentiation of functions on the half-line in a weighted uniform metric
S. G. Solodky, Y. A. Volynets
We consider the problem of numerical differentiation of functions defined on the half-line: the derivative , , is recovered from a finite set of perturbed F…

Regularized summation of Fourier-Laguerre series in the weighted sup-norm
S. G. Solodky, Y. A. Volynets
We consider the problem of recovering functions defined on the half-line from inexact input information. For the proposed regularizing summation methods based on Laguerre polynomia…
